SPECIFICATION formingpart 0f Letters Patent No. 722,064, dated March 3, 1903. Application tiled November 27, 1901. Serial No. 83,832. (No model.)

To all wbont t may concern:

Be it known that I, CHARLEs L. WEICHELT, a citizen of the United States, and a resident of the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Mercerizing-Machines, of which the following is a specifica tion.

My invention relates to improvements in mercerizing-machines, and more particularly to improvements in the manner of-carrying the rollers which carry thel yarn to be inercerized.

In the accompanying drawings, forming part of this specification, and in which similar letters of reference indicate similar parts throughout the several views, Figure l is a front elevation of' a pair of rollers for a mercerizingmachine embodying my improvements; Fig. 2, a side elevation of Fig. l; Fig. 3, a section ofL Fig. l on line 3 3; Fig. 4 a sect-ion of Fig. l on line 4 et.

a is the upper and b the lower roller of a pair of mercerizing-rollers; c, a frame carrying a fixed bearing cl, which centrally supports roller a.

ef are brackets forming part of or bolted to frame c, the outer ends of which carry or form bearings g 7L for the outer ends of roller a. The `lower end of frame cis preferably bifurcated and carries a bearing t', which carries centrally the roller b.

j is a bracket movably carried by the lower end of frame c and preferably passing through this frame, as shown in Fig. 4, the lower side of which carries bearing t' and the outer ends of which form or carry bearings la Z, which support the ends of roller b. The bracket j preferablyis furnished with flanges m, which bear against the sides of the frame c, as shown in Figs. l and 4, which prevent any movement in the bracket other than the vertical movement necessary for the adjustment of the lower roll b. Both the bracketj and the bearing 't' bear against the inner sides of the bifurcation in frame c, which arrangement prevents any sidewise movement of these parts. The bracket j is tapped out to form or carries a nut fn, which is adapted to receive a screw o, the upper end of which carries a bevel-gear p, which meshes with and is driven by a gear r, which may be rotated through a shaft s and any suitable crank or handle. (Not shown.) The rotating of screw o in one direction serves to move the roller l) and its connected parts toward the roller a, while its rotation in the opposite direction serves to move roller b and its connected parts away from roller c.

The frame c and its connected parts may be carried in any convenient manner, the lower roller and part of the frame c being adapted to be immersed, first, in the mercerizing solution; second, in the neutralizing solution, and finally in the washing solution.

The yarn to be mercerized is originally in skeins, which are placed over the rollers ot l), after which these rollers are separated, as described, in order to stretch the yarn, as is necessary during the process of mercerization.

During the mercerization of the yarn the rollers a b are rotated in any convenient manner, so that the skeins will be thoroughly saturated with the solution. In practice it is necessary that the lower roller only beimmersed in the solution and that the rollers be rotated so that different parts of the yarn be brought successively into and out of the solution. If one roller be rotated, the yarn passing around both rollers will act as a belt to drive the other roller. Hence itis only necessary to drive one of them, and I have shown one end of the upper roller furnished with a squared shoulder t, which may be received by a square socket o, which carries a gear w, which may be driven in any well-known manner to rotate socket o and roller ct.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In a mercerizing-machine, in combination, a bifurcated frame, parallel rollers carried by said frame one of which is movable relative tothe other, a xed bearing in which one of said rollers is carried, a nut carried by or forming part of said movable bearing, a screw, carried by said frame, entering said nut, a bevel-gear carried by said screw, a bevel-gear carried by said frame meshing with said first gear, and means whereby said second bevel-gear may be rotated.

2. In a mercerizing-machine, in combination, a bifurcated frame, parallel rollers carried by said frame one of which is movable relative to the other, a fixed bearing carried l the other, a fixed bearing Carried by said by said frame in which one of said rollers is frame in which one of said rollers is carried, a carried, a movable bearing, passing through movable bearing carried by said frame in the bifurcated part of said frame and furwhich the other roller is carried, a nut carried nished with flanges adapted to engage the by or forming; part of said latter bearing, a sides of said frame,ad apted no carry the other screw carried by said frame engaging said roller, and means carried by said frame for nut, and means whereby said screw may be CHARLES L. WECHELT.
